Here is your rule on delay of game

Officially, Grossman’s skate appears to be in the defensive zone, but the puck does not. In every other rule, the placement of the puck is key. Maybe they thought he “deliberately” shot the puck out. Who knows.

Rule 63 – Delaying the Game

63.1 Delaying the Game – A player, goalkeeper or a team may be penalized when, in the opinion of the Referee, is delaying the game in any manner.

63.2 Minor Penalty – A minor penalty shall be imposed on any player, including the goalkeeper, who holds, freezes or plays the puck with his stick, skates or body in such a manner as to deliberately cause a stoppage of play. With regard to a goalkeeper, this rule applies outside of his goal crease area.

A minor penalty for delay of game shall be imposed on any player or goalkeeper who deliberately shoots or bats the puck outside the playing area during the play or after a stoppage of play.

When any player or goalkeeper, while in his defending zone, shoots the puck directly (non-deflected) out of the playing surface, except where there is no glass, a penalty shall be assessed for delaying the game. When the puck is shot into the players’ bench, the penalty will not apply. When the puck is shot over the glass ‘behind’ the players’ bench, the penalty will be assessed.
